
Frequency and amplitude setting: click the frequency and amplitude of Audio Source 1 or 2
in the window, and set the output frequency and voltage amplitude of the corresponding
audio source. This value can be entered with number keys on the front panel or changed
step by step with the UP and DOWN key. The output voltage and amplitude of the noise
source can be changed in the same method.

Setting of output port: as shown in Fig. 4-28, select the audio or noise signal transmission
to the audio output port and audio box speaker by clicking the drop-down menu on the right
side of the output port in the audio source window or setting the right menu.

CAUTION:
As the loading capacity of the audio output port is limited, the
average power of the noise source and the amplitude of the audio
output will be limited correspondingly. When two audio sources
are used for output at the same time, the sum of their output voltage
must not exceed the maximum voltage of each output.
